Subject: [PATCH V3 06/11] power: charger-manager: Concentrate scattered
 power_supply_changed() calls.
Date: Fri, 19 Dec 2014 17:55:18 +0900

Current charger-manager calls power_suuply_changed() whenever charging
status is changed. This patch removes seperated power_supply_changed()
use and let it be called at end of try_charger_enable() function which
is called to set charging/discharging.
